ROVlNG-CAN.

SPECIFICATION forming part of Letters Patent No. 757,082, dated April 12, 1904. Application filed September 17, 1897. Serial No. 651,979. (No model.)

To all whom it may concern:

Be it known that I, EMERY ANnRnws, a citizen of the United States, residing at Kennebunk, in the county of York and State of Maine,

have invented certain new and useful Improvements in Roving-Cans, of which the following is a specification, reference being had therein to the accompanying drawings.

The principal aim of my invention is to pro- I duce a novel and improved construction of roving-can or sliver-can having the body composed of paper-board, leather-board, leatheroid, or other comparatively heavy and strong flexible sheet material and which shall have 5 a smooth and unbroken inner surface and an exterior reinforcing-ring to take the wear during the use of the can.

The invention will be described first with reference to the accompanying drawings, in

which latter I have illustrated the manner of reducing the same to practice, and afterward will be particularly pointed out and distinctly defined in the claims at the close of this specification.

5 In the drawings, Figure 1 shows in elevation a roving-can embodying my'invention. Fig. 2 shows in edge view a blank such as I employ for the can-body. 'Fig. 3 shows the said blank in elevation. Fig. 4 shows in edge 3 view a blank such as I employ for the min forcing-band. Fig. 5 shows the said blank in elevation. Fig. 6 is an enlarged perspective view of the bottom or lower end of a can embodying my invention, certain portions being broken away in order to show features of the construction which otherwise would be concealed.

As is well known, roving-cans or sliver-cans are employed in the manufacture of fibrous 4 materials for the reception, temporary storing, and transportation from one machine to another of the loosely-compacted continuous roll-like collections of fibers known as rovings or slivers which are delivered from the fiber-discharging devices of carding-engines, drawing frames, and the like. As a roving or sliver flows from the machine in which it is produced into the so-called can which is provided for its reception it is loosely coiled within the can, and afterward it is drawn I out of the can by the feeding devices of the succeeding machine. On account of the looselycompacted and slightly-coherent condition of the fibers composing a roving or sliver it is important that the interior of the can should present a smooth and unbroken surface not liable to catch and tear or break the roving or sliver as the latter is being delivered into or from the can.

In the drawings, 1 designates the body of a 6 roving-can or sliver-can made in accordance with my present invention. This is formed of an oblong sheet 11, Fig. 8, of material such as aforesaid. In the can the said sheet is bent into cylindrical form, with its lateral edges 5 brought together. Heretofore in practice it has been customary to cause the said lateral edges to overlap and then secure them together by cement or rivets. This overlapping has proved objectionable, since it forms projecting ridges or shoulders extending lengthwise of the can-body on both the outside and the inside of the same. The ridge or shoulder on the inside catches the fibers of the roving or sliver, thereby interfering with the 7 5 free running of the roving or sliver and tearing the latter. That on the outside has been i found objectionable on account of producing a bulge in the reinforcing or protecting band, termed kicking-band, which has been ap- 8O plied to the outside of thecan at the lower end of the latter. In order to do away with these ridges or shoulders and obviate their disadvantages, I cause the lateral edges of the sheet 11 to butt against each other in the com- 5 pleted can, as shown clearly in Fig. 6. This renders both surfaces of the can-body smooth and unbroken. For the purpose of joining together the said butted edges I employ a bridging or joining strip 2, which is applied 9 to the exterior of the can-body and extends lengthwise thereof. It covers and conceals the meeting line or joint of the said edges. (See Fig. 6.) It is secured in place by means of lines of rivets 3 8 or other suitable fastenings ,which will not produce projections within the can-body to catch the roving or sliver, the said lines being located on opposite sides of the said meeting line or joint. Thereby the can-body is held in its cylindrical form. A suitable bottom is applied, as at 17, Fig. 6.

The reinforcing or kicking band which is applied to the lower end of the can to receive the wear which is incident to the use of the can is designated 4 in Fig. 6. One or more of these bands may be employed, as deemed most desirable, and the width of the band may be varied as desired.

The bridging or joining strip 2 extends to the lower edge of the can-body, and since it is desirable to avoid a bulge of the kickingband (designated 4 in Fig. 6) the latter is formed of a proper length to permit the edges at the ends thereof to butt against the side edges of the lower portion of the bridging or joining strip 2. (See Fig. 6.) The band 1 and strip 2 preferably are formed of material of the same thickness, so that when the band is in place its exterior surface shall be flush with that of the strip 2. The ends of band 1 are united to each other by means of a strip 5, formed of thin and strong materialsuch, for example, as sheet metal-which overlies the lower end of strip 2, while the lateral edges of the said strip 5 overlie the ends of band 4 and are secured thereto by rivets 6 or other securing devices. The increased thickness, due to the presence of the uniting-strip 5, is not prominently noticeable.

Rivets are used in securing the parts of the can together, since they do not form projections on the inner surface of the can to catch the roving that is placed in the latter.

When it is desired to ship roving-cans in knockdown condition, the bridging or joining strip 2 may be secured by rivets along one edge of the sheet 11, which is to constitute the can-body, leaving about one-half of the width of the said strip overhanging the said edge. A line of holes, as 15, may then be produced in thefree edge-of the joining-strip, and a line of rivets may be applied to the opposite edge of the sheet 11, as indicated in Fig. 2, without, however, being riveted-down. To prevent the rivets or like fastening devices from getting out of the holes which contain them during transportation or handling, a paper tape 16 may be pasted over the heads of said rivets. This tape may be moistened and removed after the tube has been secured in its final form. The kicking-band may be prepared at the can factory in similar manner for shipment by connecting a joining-strip 5 along one edge thereof with one end of a strip 41 for the body of the band, as by a line of rivets or the like fastening devices at 6, the free edge of said strip 5 being formed with the line of holes &4: and the free end of strip 11 having the corresponding line of rivets or the like fastening devices &5. For the purpose of shipment a number of body-blanks prepared as aforesaid may be packed and fastened together in their flattened-out condition. The blanks for the kicking-band may be similarly packed. This will enable a very great economy to be effected in the cost of shipping and packing and the handling may be effected with greater convenience. When the package arrives at its destination, the respective blanks for the canbodies can be bent readily into cylindrical form and the rivets on the free edge of the sheet 11 inserted into the holes 15 and headed. Similarly a blank for a kicking-band may be bent into shape, its ends may be secured together, and it may then be applied to the body of a roving-can.

I do not herein claim the prepared blank for the body of a roving-can nor the means to retain the rivets or other fastening devices in place during the transportation and handling of the blank, inasmuch as these are made the subject of claim in my application for United States Letters Patent filed December 6, 1901, Serial No. 8 1,904.

What I claim is- 1. A roving-can comprising a sheet of flexible material forming the cylindrical flangeless body of the can and having straight lateral edges butted together to obviate the production of shoulders either inside or outside said body,the said body having a smooth inner surface free from projections to catch the fibrous material which is contained within the can, a joining-strip overlying the joint at the outside of the said body and having its opposite edges secured to the exterior of the butting edges of the said sheet, and a kicking-band encircling the said body, the proximate or meeting edges of the kicking-band and joining-strip being butt-jointed to obviate the formation of a projection, substantially as described.

2. A roving-can comprising a sheet of flexible material forming the body of the can and having its lateral edges butted together, a joining-strip overlying the joint and having its opposite edges secured to the butting edges of the said sheet, a reinforcing-band encircling the body and having its ends brought adjacent the opposite edges of the said joiningstrip, and a second joining-strip overlying or bridging the first joining-strip and having its ends secured to the said endsof the reinforcing-band, substantially as described.

3. A roving-can comprising a sheet of flexible material forming the body of the can and having its lateraledges butted together, a joining-strip overlying the joint and having its opposite edges secured to the butting edges of the said sheet, a reinforcing-band encircling the body and having its ends brought adjaeent the opposite edges of the said joiningstrip, and a second joining-strip of thin sheet metal overlying or bridging the first joiningstrip and having its ends secured to the said ends of the reinforcing-band, substantially as described. 10
